MAINTENANCE

STORAGE

Proper storage preparation is required for trouble-free
operation and pressure washer longevity.
Gasoline stored for as little as 30 days can deteriorate,
causing gum, varnish, and corrosive buildup in fuel lines,
fuel passages, and the engine. This corrosive buildup
restricts the flow of fuel, which can prevent the engine
from starting after a prolonged storage period. The use
of fuel stabilizer significantly increases the storage life of
gasoline. Full-time use of fuel stabilizer is recommended.
Follow the manufacturer's instructions for use.
Never store a pressure washer with fuel in the tank
indoors or in a poorly ventilated area where the fumes
can come in contact with an ignition source such as
a pilot light of a stove, water heater, clothes dryer, or
any other gas appliance, or a spark from an electric
appliance.
STORAGE TIME
Less than 1 month
2 to 6 months
6 months or longer
STORED FOR LESS THAN 30 DAYS
• Allow the pressure washer to cool a minimum of 30
minutes before storage.
• Wipe the pressure washer with a moist cloth. Clean any
debris from the muffler cooling vents.
• Store the pressure washer in a well-ventilated, clean,
dry location away from sparks, open flames, pilot lights,
heat, and other sources of ignition such as areas with
a spark-producing electric motor or where power tools
are operated. Store in an area out of direct sunlight.
• Do not store the pressure washer or gasoline near
furnaces, water heaters, or any other appliances that
produce heat or have automatic ignitions.
STORED FOR OVER 30 DAYS
Even properly stabilized fuel can leave residue and cause
corrosion if left long term. If storing the pressure washer for
two to six months, drain the float bowl to prevent gum and
varnish buildup in the carburetor.

NOTICE
RECOMMENDED PROCEDURE
No service required.
Fill with fresh gasoline and add
gasoline stabilizer. Drain the
carburetor float bowl.
Drain the fuel tank and carburetor
float bowl.

WINTER STORAGE

Make sure the pressure washer hose is free of all water
before storing for winter. In order to prevent corrosion
and keep the water pump from freezing you will need to
add RV (non-toxic) antifreeze or similar pump-protection
specifically made for pressure washers. Follow the
manufacturer's instructions for use.
DRAINING THE FLOAT BOWL
1. Turn the fuel tank valve to the OFF position.
2. Locate the drain screw on the bottom of the carburetor
float bowl.
3. Place an appropriate gasoline container under the drain
screw to catch the drained fuel.
4. Loosen the float bowl drain screw and allow the fuel to
drain. Tighten the float bowl drain screw.
DRAINING THE FUEL TANK
If storing the pressure washer for longer than six months,
drain the fuel tank to prevent fuel separation, deterioration,
and deposits in the fuel system.
1. Drain the float bowl.
2. Unscrew the fuel tank cap. Remove the fuel screen filter
by slightly compressing it while removing it from the
tank.
3. Using a commercially available gasoline hand pump
(not included), siphon the gasoline from the fuel tank
into an approved gasoline container. DO NOT use an
electric pump.
4. Reinstall the fuel screen filter and the fuel tank cap.
5. Push the battery switch to the OFF position.
6. Disconnect the battery quick-connect plugs.
7. Remove the spark plug.
